Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed. June 23, 1920. Serial No. 391.098

To all whom it may concern:

Be it known that I, LGUIS L. LASOTA, a citizen of Poland, residing atLackawanna, in the county of Erie and Stateof New York, have inventedcertain new and useful Improvements in Car-Couplings, oi: which thefollowing is a specification.

This invention relates to certain new and useful improvements in carcouplers and has for its primary object. to provide a car couplerwherein each coupling block carries a slotted link and an engaging hookto constitute a double connection between the coupling blocks. a

A further object of the invention resides in the provision ofcouplingmechanism for cars wherein there is provided a coupling linkcarried by each block for engagement with a keeper hook carried by theopposite block with an operating lever on each block adapted forsimultaneous releasing movement of the two connecting link members.

lVith the above general objects in view and others that will appear asthe nature of the invention is better understood, the same consists inthe novel form, combination and arrangement 01 parts hereinafter morefully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicatecorresponding parts throughout the several views, a

Figure l is a side elevational view of two connected coupling blocks,

Fig. 2 is a longitudinal sectional. view of the same with the couplinglinks lowered into engaging position with the keeper hooks,

Fig. 3 is a longitudinal sectional view similar to Fig. 2 showingone ofthe arms for releasing the coupling link in its elevated position withthe coupling link dlsengaged from the keeper hook, i a

Fig. 4 is a horizontal sectional view taken on line Il -IV of Fig. 1showing the two compartments in one coupling block for coutaining acoupling link and keeper hook,

Fig. 5 is an end elevational view of one of the coupling blocks,

Fig. 6 is a verticalsectional view taken on line VI-VI of Fig. 2 showingthe operating arm for the adjacent coupling link in its loweredposition, and

Fig. 7 is a perspective view of the operating arm for the coupling linkdetached from the coupling block.

The coupling blocks disclosed in the ac companying drawings being ofidentical construction, only one 01' said blocks will be describedindetail, each coupling block comprising a connecting bar 1 having anenlarged rectangular head 52 at the outer end thereof. The block 2 isprovided with a pair of end entrance compartments 3 and 41 for housingthe coupling link 5 and keeper hook 6 respectively, said compartments 3and at being separated by a central partition 7.

The compartment 3 is provided with an inclined upper wall 8 terminatingat the outer end of the block 2 while the lower end of theentranceopening to the compartment 3 is provided with an abutment wall9.

The coupling link 5 of the type best illus trated in Figs. 2, 3 and t ispivotally mounted. at its inner end upon the transverse bolt 10extendingthrough the compartment t and the rear slot 11 communicatingwith the compartment 3, the connected link 5 being pivotally mounted forvertically swinging movement. The forward end of the coupling link 5 isprovided with a longitudinal slot 12 closed at the outer end by the wall13 having an inner beveled surface 14 and an outer beveled surface 15.

The keeper hook 6 is positioned within the compartment 4: and throughwhich the bolt 10 passes, as indicated in Figs.2, 3, and 4:, and thecoupling linksand hooks of coiiperating blocks are positioned to presentthe outer projecting slotted end of the coupling link for reception inthe opposite compartment 4.- for engagement with the keeper hook 6. T heblocks in being moved toward each other will cause the outer beveledends 15 of the coupling link ends 13 to ride over the beveled edge 16 ofthe forward lower abutment wall of the compartment 4;, there by slightly.to elevate the free ends of the coupling links to position for slidingen- Hagementwith the keeper hooks 6 and cansing positioning of theslotted portion of the coupling links over the keeper hooks forreception thereof to retain the coupling blocks connected. K

In order to efi'ect arelease of the coupling links from thekeeper hooksand to disconnect the coupling blocks2, a vertically shiftable operatingarm is carried by each block, the arm being shown in detail in Fig. Tasembodying a vertical shank 17 carrying an angular extension 18 adjacentits lower end with a cross head 19 at the free end of the extension andprovided upon the upper end CAR-COUPLING. r.

thereof with operating faces and 21. The bottom wall of the compartment3 is provided with a T-shap'ed slot, the leg 22 of each slot extendinglongitudinally of the wall while the cross head 2-3 thereof extends tothe compartment 4 and is alined with a vertical slot 24 in the partition7. A vertr calslot is provided in the upper wall of the block and is invertical alinement with the rearend of the slot 22. The operating arm isintroduced into the block through the lower slotted end thereof, theshank 17 entering the slot 22 and passing into the opening 25 forprojection above the block 2 andretained in position by the link 26. Theshank extension 18 passes through the slot 22 while the cross head 19enters the head portion-23 of the slot. The operating face 21 extendsinto the compartment 3 \vhile the operating face 20 extends into thecompartment 4 and both operating faces underlie the coupling links 5.

VVhen it is desired to uncoup le the blocks 2, either of the operatingarms 17 is elevated vertically to shift the head 19 to elevate thecoi-ipling link 5 to the position shown in Fig.

The operating face of the head 19 engages the link 21 carried by thesame block while the operating face 20 engages the end of the link 5carried by the opposite block. Either of the operating arms 17 may beemployed for' releasing the coupling links 5 from the keeper hooks 6 andoper'atlng means of any preferred type may be at tached to the arm links26. As shown in Figs. 2 and 6, the lower end of the head 19 is taperedand projects downwardly through the head portion '23 of the T slot andmay be struck with a suitable implement to start the elevating movementof the operating arm.

While there is herein shown and described the preferred embodiment ofthe present invention, it is nevertheless to be understood t-h-at, minorchanges may be made there-in Without departing from the spirit and scopeof the invention as claimed.

WVhfat-is claimed as new is 11A car coupler of the type describedcomprising companion coupling members each embodying a head, there beingcompartmentsin said head and a partition separating the compartments, abolt extending transversely of said compartments, a coupling-link wit-hmone of said compartments 7 and supported on said bolt, and a keeper hookin the other compartment pivoted upon said bolt,-th'e coupling linkofoneblock engaging the keeper ofthe opposed block.
